BOTTLE-CLOSURE.

Specification of Lette'rs Patent.

Application filed November 6, 1912. Serial No. 729,758.

troit, in the county of vWayne and State of IMichigan, have invented certain new and useful Improvements in Bottle-Closures, of

which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to bottle closures of that type comprising a-flat disk of paper or similar material adapted to seat upon a narrow ledge in the mouth of the bottle.. Such closures, which are extensively used in connection with milk bottles and for similar purposes, have the advantage, first, that they are perfectly sanitary; second, that they form an effective seal; and third, that they are adapted to be rapidly engaged with the bottles by machines. There is, however,

an objection to their use, which is the dilii-A culty in removing them. This we haveovercome by an improved construction, which, While retaining all of the advantages above set forth, has the additional advantage of being easily removable.

In the drawings: Figure 1 is a perspective View of a bottle showing our improved closure applied thereto. Fig. 2 is a cross section. thereof, the disk being illustrated as depressed whereby the finger may be inserted beneath the strip. Fig. 3 is a view taken transversely through Fig. 2. Fig. 4 is a plan view of the closure; Fig. 5 is a View similar to Fig. 4, showing a modification;

'and Fig. G is a view taken transversely through Fig. 4.

A is a bottle, such for instance as a milk bottle provided with 'a shoulder or ledge Bforming a seat for a paper disk closure C.

Our improvement consists'in applying to the disk a iiat loop D, preferably of tape or ribbon, which embraces the disk and eX- tends preferably diametrically thcreacross. This loop may be made of any suitable marateneeaaug.- ri, rara'.

terial having the requisite strength and l when applied to the disk will lie adjacent to the top and bottom faces thereof, so as` not to interfere with the placing of the closures in the magazine of the machine by which they are automatically engaged with the bottles. Furthermore, the loop will not interfere with the perfect sealing of the bottle or require modification in the shape of the paper blank. l

In use, the closures may be engaged with the .bottles either by hand or by machine, the loop D extending diametrically across .the top. When it is desired to remove the closure, the pressure of the finger against the center of the top of the-disk will be sufiicient to open the space beneath the loop so that the lat-ter may be grasped between the thumb and finger. A slight pull up- Ward will be sufficient to then disengage the closure, this operation being'fa'cilitated by the transmission of the stress to the edges of the disk which are raised sufficiently to break the air seal, the disk bowing and theV edgesl being forced inwardly as vShown in F im 2.

ur construction may be manufactured at small cost and is greatly superior to those heretofore employed.

What we claim as our invention is:

A bottle closure consisting of aflexible disk adapted to be fitted into the mouth of the bottle and a narrow flerible,` band embracing said disk and extending over vthe edges and across the opposite face' thereof, the outer portion of the band normally lying adjacent to the face of the disk and movable relative thereto.

In testimony whereof we aflix our signin tures in presence of two witnesses.
